Demand Series Bookshelf Loudspeakers: The Definitive Technology Demand
Series D7 high-performance bookshelf loudspeakers deliver full-range,
room-filling sound and precise imaging in a modern, elegant styling. Featuring
technology advancements to both Definitive's aluminum dome tweeter and
midrange/woofer sections, these speaker deliver an unrivaled sweet spot,
smoother high-frequency reproduction, and three-dimensional imaging for a
technically-advanced, premium bookshelf listening experience.
1" Aluminum Dome Tweeter: The 1" annealed aluminum tweeter is
precision engineered to articulate nuance and detail in the high-frequency bands
for a crystal-clear listening experience. Offsetting the tweeter by 5° delivers
a more precise center stereo image by eliminating undesirable symmetric
diffraction off the corners of the front baffle.
- 20/20 Wave Alignment Lens: Coupled with Definitive's new 20/20
Wave Alignment Lens, the 1" annealed aluminum dome tweeter delivers smoother
high frequency response and improved dispersion for a rich and balanced
- Linear Response Waveguide: A patented Linear Response Waveguide
extends both on and off axis frequency response, while improving dispersion
for more natural mid-range timbre and more precise imaging.
Note: Because the tweeters are offset, the
bookshelf speakers are labeled for left (L) and right (R) on back of the
4" BDSS (Balanced Double Surround System) Midrange/Woofer: A patented
4" Balanced Double Surround System (BDSS) polypropylene midrange/woofer provides greater
excursion and output that results in superior midrange detail and punchier bass
compared to drivers of similar size. The speaker's balanced double surrounds
support the cone at two points to provide better mechanical stability for
longer, more linear excursion, and improved damping to suppress cone resonance.
Bass Port: A rear-firing bass port provides superior low-end extension
by smoothly transitioning air flow from the speaker into your listening area for
deep, extended bass impact while minimizing turbulence and distortion.
Hand Crafted Cabinet: The speaker cabinets are constructed from MDF
with an extruded natural bead-blasted aluminum front baffle. The cabinets are
hand-crafted, meticulously sanded, painted with five layers of premium black
gloss paint, and then buffed for a near-mirror finish (Level 6) for an
uncompromising look in your home.
Acoustically Transparent Magnetic Grille: Each bookshelf loudspeaker
also comes with an acoustically transparent black magnetic grille. The included
acoustically transparent magnetic black speaker grilles provide natural,
uncolored sound when placed on the speaker, and remove easily when you want to
enjoy looking at them fully uncovered.
Gold-Plated Binding Posts: Each bookshelf speaker is outfitted with a
set of gold-plated, 5-way binding post terminals to connect bare speaker wire
(up to 10AWB), pin-connectors, spade-lugs, and banana plugs (single or dual).
Note: In order to use banana plugs, you must completely unscrew
the binding-post terminals and remove the rubber caps. Once you have removed
the rubber caps, you can fully screw down the binding-post terminals and
connect your banana plugs (sold separately).
Mounting Options: The Demand Series D7 bookshelf speakers can simply
be placed on a speaker stand, desk, table or shelf. Definitive offers a speaker
stand (735DST1, sold separately) specifically designed for the Demand Series
bookshelf speakers. Integrated rubber pads on the bottom of the speakers provide
stability and protection. Each speaker is also fitted with a back panel 3/8" threaded
insert to wall mount the speakers using optional brackets (sold separately).
Note: Currently Crutchfield does not offer a wall bracket with 3/8"
mounting hardware. However, you can use the Pinpoint side-clamping brackets
(sold separately - see Accessories tab) to wall mount the speakers
Placement: The D7 bookshelf loudspeakers and your main
listening position should be setup in an equilateral triangle that measures
7-10' from each speaker and the listening position. The speakers should be
placed approximately 2-6' from side walls and 2-4' from back walls. The speakers
should be mounted as close to ear level as possible with the listening position. Toeing the speakers in slightly, toward your listening area will
provide stronger stereo imaging.
